Abstract: A solar tracker including at least one pair of piers configured to be secured in the ground and defining a span between the pair, a bearing supported on the pier, and a torque tube supported in the bearing such that the bearing enables rotation of the torque tube, the torque tube including a double wall thickness area, wherein the double wall thickness area limits deflection of the torque tube along the span.

Abstract: An elevated outlet assembly includes a tripod that has a base and a plurality of legs each extending downwardly from the base. Each of the legs engages a support surface thereby elevating the base upwardly from the support surface. A disk is disposed on the base and a plurality of female electrical outlets is each integrated into the disk to receive a power plug from an electronic device. Each of the female electrical outlets is elevated when the tripod is positioned on the support surface to inhibit the power plug from the electronic device from coming into contact with moisture on the support surface. A power cord is coupled to and extends away from the disk and the power cord can be plugged into a power source to supply electrical power to the respective electronic device.

Abstract: A surgical positioning aid includes a n inflatable pillow with a non-inflatable sleeve. The non-inflatable sleeve has two substantially parallel attachment regions secured to a panel of the inflatable pillow and two open end portions to provide access between the non-inflatable sleeve and the inflatable pillow. The space between the non-inflatable sleeve and the inflatable pillow can be telescoped onto a surgical support post in proximity to an operating table. Air then can be directed into the inflatable pillow so that a patient can be supported relative to the post without creating pressure points on the patient.
